Heligen
is a completely new, innovative, product in the modelling world - an
engine driven brushless alternator to supply power to your 2.4Ghz radio
system. This first version fits OS 50 or 55 Hyper engines and is
therefore aimed at the helicopter market. Future versions will suit
other engines.
The Heligen alternator has been designed to fit
directly onto the back of the engine, taking its drive from the
crankshaft. After passing through the Rectifier/UBEC module this gives
a voltage-stable, high current source to the radio system while the
engine is running, leaving the usual Rx battery to act as a backup.

Pilot
concern about the state of charge of the Rx battery is eliminated, and
battery capacity no longer limits your flying session.
